Against Wakefield, they were made to pay for poor starts to both halves.

Giants half-back Danny Brough was sent to the sin-bin for a high shot on Reece Lyne during a sloppy opening to the first period, although he returned to set up Connor's first-half score with a jinking run and sharp pass.

That left the hosts only six points behind at the interval, but there was to be no way back for Huddersfield once Grix's loose pass had gifted Johnstone the chance to coast over for his sixth Challenge Cup try of the season.
